AHADEX Tools — Free browser tools that never upload your files

AHADEX Tools is a collection of 3 free utilities for everyday digital work — image conversion, PDF handling, text processing, developer helpers, and QR code generation. Every tool runs entirely inside your browser. Your files and tool input are processed locally and are not uploaded to our servers or stored anywhere. (Anonymous analytics and advertising scripts load separately — see the Privacy Policy for details.)

What AHADEX Tools does

AHADEX Tools is a single-page collection of independent utilities, each solving one specific problem without signup, watermark, or file-size limit. The tools fall into six categories:

• Image tools — convert between JPG, PNG, and WebP; compress; resize; crop; view metadata; turn photos into sketches or cartoons.
• PDF tools — merge; split; rotate; convert PDF pages to PNG or JPG; extract text; build image-only PDFs.
• Developer tools — format and validate JSON; encode URLs; generate UUIDs; encode Base64; generate strong passwords.
• Text tools — count words; count characters against platform limits; convert between 12 case styles.
• QR & barcode tools — add scannable QR badges to photos; generate 1D barcodes in nine formats.
• Design & documents — design visiting cards; build ATS-friendly CVs; generate complete favicon sets.

How the tools work

Every tool is written in JavaScript and runs entirely in your browser using standard web APIs — the HTML5 Canvas API for images, pdf-lib and pdf.js for PDFs, and the Web Crypto API for cryptographic operations. When you upload a file, the file is read into memory by your browser and never travels over the network. You can verify this yourself: open your browser's developer tools, switch to the Network tab, and use any tool. You will see zero outbound file-upload requests. You can even turn off Wi-Fi after the page loads and every tool continues to work.

Why browser-based matters

Most online tools upload your files to a server. For passport photos, contracts, medical records, ID scans, and unreleased design work, that means a copy of your file sits on someone else's computer for minutes, hours, or longer. Some services claim to delete files immediately. Even so, the file has already been transmitted. AHADEX Tools avoids that entire class of risk by never sending anything anywhere.

Who AHADEX Tools is for

• Freelancers and small business owners — sending deliverables, preparing invoices, compressing images for clients.
• Students and researchers — merging PDFs for submissions, converting lecture slides to images, building CVs.
• Developers — formatting JSON, debugging URLs, generating UUIDs and Base64 without opening an editor.
• Designers and photographers — batch-converting images, creating favicons, adding watermarks, extracting colour references.
• Anyone who values privacy — anyone who would rather not hand their documents to an unknown server.

Featured tools

• CV Builder — build a professional A4 CV and export a selectable-text PDF that ATS software can parse.
• Photo QR Code — add a real scannable QR badge to any photo for WhatsApp, WiFi, Instagram, or a vCard.
